Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Airy 1830 ellipsoid | Statement: [British National Grid, usesEllipsoid, Airy 1830 ellipsoid]

Target entity: Airy 1830 ellipsoid
Context triple: [British National Grid, usesEllipsoid, Airy 1830 ellipsoid]

• A. Airy Modified ellipsoid
  The Airy Modified ellipsoid is a slightly adjusted version of the Airy ellipsoid used as the reference surface for mapping and geodetic calculations in systems such as the Irish grid reference system.
• B. Maclaurin spheroid
  A Maclaurin spheroid is an oblate, rotationally symmetric ellipsoidal figure used in astrophysics and geophysics to model the equilibrium shape of a uniformly rotating, self-gravitating fluid body.
• C. Roche ellipsoid
  A Roche ellipsoid is an equilibrium shape assumed by a self-gravitating fluid body that is tidally distorted by a nearby massive companion, important in the study of close binary systems and tidal interactions.
• D. Humboldt meridian
  The Humboldt meridian is a principal survey meridian used as a reference line for land surveying and mapping in parts of northern California.
• E. Earth gravity model
  The Earth gravity model is a mathematical representation of Earth's gravitational field used for precise positioning, navigation, and geodetic calculations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions

Entity: Airy 1830 ellipsoid
Triple: [British National Grid, usesEllipsoid, Airy 1830 ellipsoid]

The Airy 1830 ellipsoid is a reference ellipsoid defined in the 19th century for geodetic calculations in Great Britain, forming the basis of traditional mapping systems such as the British National Grid.
